129##   up in a subdir.  Having to rename by hand is ugly.
130##   (We might end up doing this anyway to support other compilers.)
131## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
132##   -MM, not -M (despite what the docs say).
133## - Using -M directly means running the compiler twice (even worse
134##   than renaming).
